Cannot turn on Eigen and boost / regex at the same time

Question

I can turn on each library separately, but as soon as I try to turn them on at the same time, I get a lot of errors. I am using Boost v1_55_0 and Eigen v3.2.1. Any idea what could be the problem?

My inclusions are as follows:

#include <boost/regex.hpp>
#include <Eigen>

I insert the first two errors below, there are more than 100 of them.

Error   1   error C1189: #error :  The Eigen/Array header does no longer exist in Eigen3. All that functionality has moved to Eigen/Core.   c:\local\eigen\array    8   1   Project1

Answer 1

Boost includes a C ++ 11 std::arrayheader array, but your include path collects a header array(<clearly outdated) from Eigen. You must be in a file system that does not distinguish between files in each case.

It seems like the correct way to include the Eigen header:

#include <Eigen/Eigen>

., , . include, , Eigen/, , Eigen/ .
